The major anthocyanin compound in buckwheat sprouts was determined to be cyanidin 3-O-rutinoside (C3R), based on HPLC data and MS/MS spectra. Investigation of the content of phenolic compounds in commercial buckwheat sprouts indicated that hypocotyls are abundant in C3R and rutin, whereas all of the detected flavonoids are abundant in cotyledons. The superoxide anion radical-scavenging activities (SOD-like activities) of phenolic compounds in buckwheat sprouts and their contents indicated that rutin, isoorientin, and orientin contributed mainly to the SOD-like activity of the extract from buckwheat sprouts. In contrast, the contribution of C3R was substantially lower than that of flavonoids.
